Frequently anticipated questions:

What does this data set describe?

Title: Zooplankton, NE Chukchi Sea, 2008-2012
This data set was collected as part of the Chukchi Sea Environmental Studies Program (CSESP), a multi-year, interdisciplinary ecological study focused on areas in outer continental shelf oil and gas leases in the northeastern Chukchi Sea. In 2008 when the program began, two 30 x 30 nautical mile study area boxes were developed around areas of interest to ConocoPhillips and Shell. The ConocoPhillips study area (named Klondike), and the Shell study area (named Burger) became the focus of data collection. Data were collected from these two study areas again in 2009. Then, in 2010, Statoil joined the program, and a third study area, Statoil, was created and sampled as well as Klondike and Burger. In 2011 and 2012, the scope of the study area was expanded to include the Hanna Shoal Regional Study Area.
The CSESP interdisciplinary studies include acoustic monitoring, baseline chemistry, benthic ecology, chemical oceanography, fisheries ecology, marine mammal ecology, physical oceanography, plankton ecology and nutrients, and seabird ecology.
This data set contains zooplankton data gathered in the northeastern Chukchi Sea during the 2008-2012 open water season. Zooplankton data parameters include the cruise ID, the station the sample was collected from, the local date and time of sample collection, the gear used to collect the sample, the depth of the water where the sample was collected, latitude and longitude of the location the sample was collected, zooplankton density, the scientific name and life stage of the zooplankton, the biomass of the species, the title of the report the data set supports, the name of the contractor who recorded and analyzed the data, and any additional notes concerning the record.
Edtion 3 Updates (March 2014): Incorporated PI edits, added keywords, deleted attribute DENSITY_M3 and added attribute ABUNDANCE_M3. Additional Disclaimer of Liability added.
Edition 2 Updates: Appended 2011 data, updated metadata to include details about 2011 season, geographic projection updated from NAD83 to WGS84.

Why was the data set created?

The objectives of the Chukchi Sea Environmental Baseline Studies Program are: 1. To provide data for pre-exploration and development-related activities 2. To provide data for permit applications 3. To provide input to planning of future operations and associated mitigation 4. To provide additional baseline data that can be used to assess and measure the potential environmental effects of offshore oil and gas exploration and development in the northeastern Chukchi Sea

How was the data set created?

  1. What methods were used to collect the data?

    Method 0 of 1
    Type: Field and Lab

    Smaller mesozooplankton were collected at alternate stations by paired 150–μm-mesh ring nets of 60-cm diameter hauled vertically from within 3 m of the bottom to the surface at 0.5 m s. The volume of water filtered was measured by one-way General Oceanic flowmeters in each vertical net. To target larger, more mobile zooplankton, a set of 60-cm diameter 505–μm Bongo nets were deployed in a double oblique tow with the ship moving at an average speed of 2 kts. Upon retrieval, one sample was preserved in 10% buffered formalin, and the other in 95% ethanol (required for molecular identification). When present, large cnidarians and ctenophores were removed, measured, photographed, identified and then discarded prior to sample preservation. During taxonomic processing, all larger organisms (primarily shrimp and jellyfish) were removed, enumerated, and measured then the sample was divided with a Folsom splitter until the smallest subsample contained about 100 specimens of the more abundant taxa. Specimens were identified to the lowest taxonomic category possible, staged where appropriate, enumerated, and measured. Increasingly larger fractions were examined to identify, measure and enumerate the larger, less abundant taxa, particularly in the 505–μm net which typically captures the largest taxonomic diversity. A minimum of 300 individual organisms were identified from each sample.

  1. How well have the observations been checked?

    CSESP Attribute Accuracy Overview When the program began in 2008, scientists collected and stored their data through a variety of methods. Vessel data were collected by individual software packages and backed up as part of the regular computer backups, which may or may not have coincided with backups conducted by the scientists. Each scientist had his or her own method for recording and storing at sea observations and data; some of these methods included paper copies.
    The TigerSoft application was developed in 2009 to better manage all scientific data collected through the CSESP. TigerSoft consists of three components: TigerObserver, TigerNav, and TigerObserver Server. Under the oversight of a data manager, these three programs worked in concert with predetermined scientific data protocols to integrate scientific observations with vessel navigation to produce standardized data sets. Data sets were backed up regularly and made available to scientists to proof and edit on a nightly basis during the cruises. TigerSoft was used each season for data collection since it's inception in 2009.
    After the conclusion of each field season, data managers merged the TigerSoft daily observation databases of each discipline and distributed the data in Excel spreadsheet format to the primary investigators of each discipline. Primary investigators reviewed their data and signed forms acknowledging the completeness and accuracy of the data. If corrections needed to be made to the data, detailed information regarding the corrections and an edited copy of the data was returned to the data manager. Examples of corrections include updated species identification and deletion of an observation event that was made in error.

  2. How accurate are the geographic locations?

    In 2009 and 2010, latitude and longitude values were obtained through a Hemisphere VS100 Heading and Positioning Receiver. The horizontal accuracy of the instrument was +/- 0.6 meters.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

  5. How consistent are the relationships among the observations, including topology?

    Each year the primary investigators spent approximately nine months analyzing their data and then produced a discipline specific annual report for CSESP and a final data set. The final data had to adhere to a predetermined data protocol and pass through a data validation tool in order to be accepted by the data manager. Data that did not pass validation were returned to the primary investigators to be corrected and resubmitted for validation.

How can someone get a copy of the data set?
